Hello I got a baffling problem with my 2017 Chevy Silverado 1500 LT with the 5.3 L and Z71 package in it. I got a U1510 code and U1501 code. The U1510 says it’s a LIN on bus communication issue. Now this was about the end of August when that happened. Looked at a few things couldn’t really figure it out and didn’t have the time to look because the truck seems to be running fine. About 4 days ago my service brake trailer starts flashing on my dash when I’m not even towing a trailer (the last time I did was about 5 days before this). Now I take it to my step father who owns a garage and has worked on chevys for years. Now the U1510 code is still  there when we scanned it but the U1501 code is gone but now on top of those codes there’s a U1037 code which is lost communication with trailer brake control module, P0562 which is low system voltage for Chasis Control Module, B127E code which is Front video display output signal, and C0800 code which is control module power circuit below voltage threshold for the power steering control module. The truck driving it runs perfectly fine, nothing abnormal at all. So thinking the trailer brake might be a separate issue we checked that out all the wiring etc and nothing wrong with it. So for the other codes we went and checked all the grounds on the truck thinking it might be a ground issue and all them seem to be good. We are starting to think maybe it’s a PCM, ECU problem because of all the random codes being thrown in every direction as well as codes in the system before disappearing. Any advice or help would be appreciated!!

Hey Nathan, did you ever find resolution to your problem? I have a 2016 Silverado 1500 experiencing the exact same symptoms and trouble codes. I've already replaced the two trailer brake modules, one by the spare tire and the other in the dash but still receiving a "Service Trailer Brake" message without towing. Also have 3 of the 4 codes you listed above. Dealer advises me to replace the battery cables but before I spend $$$ wanted to see if you had any luck. Any help is greatly appreciated.

Nathan and Jeff, any resolutions to the problems you describe above? I have a 16 silverado 1500 z71 with the same codes going off, and truck driving fine exactly like you describe. Looks like you were being prompted to switch the battery cables Jeff -- did you do that and did it work?

I still randomly get a service stabilitrack or service safety restraint system once in a few months. I used to get them fairly often. 

Replaced positive and negative battery cables, cleaned ground under passenger front fender liner and driver seat on frame rail.

Guessing its a loose connection on harness somewhere...

    • I have an Autel, works great for what it is. Can't do some specific things because you need say the GM tool, VCDS for Audi/Volkswagon and others of course. But those times are few and far between for me.   The other tool I'd like to try one day is the new Topdon scan tools. Seen several video's on them and many youtube people review them.    I've never subscribed for updates or payed to do that stuff on my Autel, so I'm sure I'm missing out on some of the updates but I'm fine with that for now.
    • I am in the market for a bidirectional scan tool so was hoping someone can help point me in the right direction. There are so many options out there it is hard to narrow down which make/model to choose.   I have always done my own vehicle work so looking to maximize capability with the scanner. Ideal price is $1k or less but would be willing to exceed if it opens up significant benefits.  Currently my 24 2500 is the newest vehicle but also have a few mid to late 2010s Subarus as well.    It seems that the Autel MP900 has a decent amount of features at a reasonable price?
    • There was talk over the last couple of years that the contract to build these trucks between GM and International would not be renewed.  International moved production of all their other trucks besides the companion CV model out of the Springfield plant some time ago when they opened their San Antonio plant.  That left Springfield only building the Silverado Medium Duty, International CV Series, and some Express/Savanna long wheelbase cutaways.  International also put the plant up for sale some time ago.  This all answered my earlier question as to why GM and International did nothing with these trucks since they were introduced, as they had basically become a market 'placeholder' with a finite life.    The Silverado Medium Duty/International CV trucks were interesting combination of a GM powertrain, electrical system, and K2XX Silverado cab with an International chassis that was supposedly designed for a step-van type vehicle they never produced.  They were manufactured in International's Springfield plant along with the IH MV series initially.  When first introduced, there was much talk that the Silverado Medium Duty/CV would eventually get a gasoline engine option along with other upgrades and GM and IH would work on a class 6/7 joint venture truck.  This was before VW bought Navistar out, after that happened no more was said.  Draw your own conclusions...   About the time talk started that the GM/IH joint venture was not going to be renewed, rumors started that GM would develop a new line of medium duty trucks themselves.  The story is the new trucks will be part of the next generation HD's due in 2028, and will still feature a 'straight rail' chassis design that the current medium duty has.  GM views this as a desirable feature that differentiates their truck from the competition.  A gasoline engine option is also expected.  As the current Silverado Medium Duty remains in production until September 2026 and there is still a lot of inventory available do not expect any official word for some time.   I believe GM remains committed to their successful partnership with Isuzu, and all the LCF models will still be available from Chevy Commercial dealers.  Isuzu is on the cusp of opening a new large plant in South Carolina and there is also speculation that this may result in new product for both Isuzu and Chevy Commercial dealers.
